| Abstract: | In the present of double solvent, little catalyst and dimethy sulfate, acephate technical was prepared from methamidophos by adding ammonia, lamination, extraction, distillation, crystallization,drying. In the industrial test, the yield of acetylating was over 95%, the yield of acephate technical was over 80%,and the content of acephate technical was over 95%. |
